What is GIS?

On the surface, Geographic Information Systems (GIS) can be referred to as computer mapping.  GIS, however, goes beyond simple line work.   This technology integrates common database operations such as querying and statistical analysis with the unique visualization and geographic analysis benefits offered by maps.  These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies.


Multiple 'layers' of geographic data can be analyzed to show relationships never before possible.  Whether analyzing forests, rivers, roads, or aiding in land use decision making, GIS has become an important tool for Josephine County.

The flight starts above the city of Cave Junction, then proceeds north, turning northwest to follow Josephine Creek.  A few more turns to the left and the viewer is flying south over mountains.  Eventually, the flight returns to its origination point.  Click here to see a visual representation of the flight plan.

This fly-through was created using Environmental Systems Research Institute's 3D Analyst extension of ArcView.  It is a standard Mpeg movie which is playable through a number of different software packages.  If your browser is set up to play .mpg files, click the image above to play the movie.  Otherwise, you can download the file by right clicking and selecting 'Save Target As' (Internet Explorer), or 'Save Link As'' (Netscape).
